Method and System for Establishing Connectionless Mesh Network Route

Abstract

Disclosed are a method and system for establishing a route in a connectionless mesh network. The method comprises the following steps of: a sink device periodically broadcasting information to one or more surrounding devices of the sink device, wherein the information comprises information indicating the sink device as a sink, a MAC address of the sink device, and a signal strength between the sink device and an external router; a non-sink device periodically monitoring information broadcast by one or more surrounding devices of the non-sink device, and determining whether the information broadcast by the sink device is present; if so, the non-sink device selecting a sink device having a highest signal strength therewith as a next hop device, and the non-sink device periodically broadcasting information to the one or more surrounding devices of the non-sink device, wherein the information comprises a number of hops from the non-sink device to the sink device, a MAC address of the sink device, and the signal strength between the non-sink device and the sink device; if not, the non-sink device selecting a device having a highest signal strength therewith as the next hop device thereof, and the non-sink device periodically broadcasting information to the one or more surrounding devices of the non-sink device, wherein the information comprises the number of hops from the non-sink device to the sink device, a MAC address of the next hop device, and the signal strength between the non-sink device and the next hop device. The present invention may enable each device to find and maintain a route having the highest signal strength to a network sink.

Description

TECHNICAL FIELD[0001]The present invention relates to a wireless communication network technology, and in particular to a method and system for establishing a route in a connectionless mesh network.BACKGROUND ART[0002]With continuous development of the wireless network technologies and emerging of various new applications, there is an urgent need for wireless networks able to access the Internet to meet sharply increasing user demands. Traditional routing based on the minimum number of hops is simple and fast; however, for a connectionless mesh network, the existing access method is somewhat limited in that a route with the minimum number of hops may not ensure the best signal. Therefore, there is a need for an implementation method for connectionless mesh communication, thereby reducing data loss rate and improving quality of service.SUMMARY OF THE INVENTION[0003]An object of the present invention is to provide a method and system for establishing a route in a connectionless mesh n...
